Grace Phipps and Garrett Clayton get friendly with a dog while out to lunch on Sunday afternoon in Venice Beach, Calif.

The two Teen Beach Movie stars grabbed some burritos for lunch before spending the rest of the day together.

Teen Beach Movie follows McKenzie (Maia Mitchell) and Brady (Ross Lynch), who find themselves literally transported into his favorite classic beach musical, set in the 1960s, about a rivalry between the surfers and bikers and a star-crossed teenage boy who likes a girl.
